The Grundfos DMX pumps are mechanical diaphragm dosing pumps. The strokes are generated by an eccentric, which moves the diaphragm by means of a spring-loaded plunger. The discharge stroke is activated by the eccentric and the suction stroke by the spring return. The DMX pumps are designed for capacities between 1.3 and 2 x 166 GPH and a maximum pressure up to 232 psi. The DMX pumps are fitted with a separation chamber. In the event of a diaphragm failure, the separation chamber prevents the pumped liquid from flooding the pump unit or other system components. It is a series of high-quality mechanically actuated diaphragm pumps suitable for many uses, such as drinking water treatment, wastewater treatment, and the pulp/paper and textile industries.
